dudes...

am in the market for a TT bike for next year.. wondered if anyone had any thoughts etc etc on good entry level TT bikes..?
i am racing in Ironman Roth next year and plan on doing a hand full of tri's to prepare for it..

I can't really afford a new one as i want to upgrade wheels on whatever i get and am also unsure of sizing.
Typically a 58cm frame for road fits me well, but i guess that doesn't mean i need the same size frame for a TT bike..

wish i had enough cash to get someone to build me one made to measure, but have to hope my lottery numbers come up first..

comments appreciated..
bikes:
Trek 9.8
Specialized Langster
Specialised Tri_Cross Comp
Viner Magnifica
and a unicylcle

    Check out the Tri forums for secondhand options, but the general consensus is that you'd go slightly smaller on the TT bike than a road bike - provided the manufacturer hasn't already compensated for it.

    Check out the fit computer on the Competitive Cyclist website - there's a Tri/TT option. I found it a far better tool than the Canyon version when I bought my Speedmax. It gives you a load of suggested measurements which you can then use to compare with the geometry data on the manufacturers' websites.
